概述
The Dytran model 3224A1 is an ultra miniature teardrop IEPE accelerometer with integral electronics, designed to adhesively mount in *ces inaccessible to other types of accelerometers and an overall weight of just 0.2 grams. Model 3224A1 i*apable of reliable operation in temperatures up to +300°F (+149°C).
Available with a 10 mV/g sensitivity, the model 3224A1 features a ceramic shear sensing element in a lightweight laser welded titanium housing, with a 3-foot (0.9-meter) integral cable terminating to a 10-32 jack. The cable is designed to mate with several Dytran extension cables.
